IMPROVEMENT IN FLUTlNG-MACHINES.

Specification forming part of Letters Patent No. 137,258, dated March25, 1873.

T 0 all whom it may concern:

Be it known that I, THEODORE STOGKMARR, of the city, county, and Stateof New York, have invented an Improvement in the Chains ofFluting-Machines, of which the following is a specification:

In what is known as the French flutingmachines endless chains are usedto efi'ect the fluting instead of rollers. This invention relates tomachines of this class; and it consists in the combination'of twochains-one having T-headed links and the other roundheaded linkswherebya fluting of novel character is produced, composed ofapproximately-circular flutes and intervening flat sur- I faces.

by pins cl d form the chains, those in the chain A having round heads aa and those of the chain B having flat Theads b b. The chains are soarranged relatively to each other that their links shall mesh or workinto one another, the heads of the links of each chain interveningbetween those of the other chain, as represented in Fig. 2.

The .fluting, as before stated, is composed of approximately-circularflutes e e and intervening flat portions f f. The circular flutes areformed by the round heads a a of the chain A, and the flat surfaces bythe flat T- heads (2 b of the chain B.

Claim.

The combination, in a flutingmachine, of the two chains A and B, the onehaving roundheaded links and the other having T-headed links,substantially as and for the purpose herein set forth.
